The root block was used as a sentinel. This means we always need to
allocate a second block on the heap, even if the set has a few small
elements.
We now use the root block: it is always the block with the smallest
offset. The logic becomes very messy if there is no sentinel; to avoid
this we still use a sentinel (a special singleton block) and return it
in when appropriate in the first, last, next wrappers.

Before this change, astutil would only do a prefix match of a new import
with all the existing ones, to try to place it in the correct group. If
none was found, the new import would be placed at the beginning of the
first import group.
This works well for new std imports, but it doesn't work well for new
third-party packages that don't share any prefix with any of the
existing imports.
Example:
import (
"time"
"github.com/golang/snappy"
)
When adding "golang.org/x/sys/unix" with astutil.AddImport, the import
is inserted as follows:
import (
"golang.org/x/sys/unix"
"time"
"github.com/golang/snappy"
)
And goimports reorganizes the imports to separate std and third-party
packages:
import (
"time"
"golang.org/x/sys/unix"
"github.com/golang/snappy"
)
We usually don't want to introduce a new import group; in most cases,
the desired behavior is separating std from third-party packages.
With this CL, new imports that don't share prefix with any existing ones
will be placed with the first group of third-party imports, if any
exist. If no third-party import group exists, a new one will be added.
In the case of our example above, this will be the new outcome:
import (
"time"
"github.com/golang/snappy"
"golang.org/x/sys/unix"
)

succeed. However, when failure occurred we would only log the error and not
interrupt the flow of the program. This would cause the program to continue with
the assumption that git-codereview had been installed correctly.
This change enhances the `go-contrib-init` command to exit with a bad status
code, after logging the failure, if installing git-codereview fails.

In the loader API, (*Config).Import, like go/build, accepts relative
paths such as ".", but (*Program).Package requires the exact path of a
loaded package. So, to find the package identified by "." we must
look at the set of packages actually loaded, which in this scenario is
guaranteed to be a singleton.
(This is a definite weakness of the loader API. In the more general
case where two or more packages are imported, it's tricky to correlate
the calls to Import with the package(s) each call actually loads.)
